Windows startup reliability release.
- Fixes the Python.Runtime.Loader.Initialize crash seen after extracting a downloaded Windows archive.
- Ships the required .NET application configuration next to KevinTex.exe.
- Pins the Windows PyWebView/Python.NET packaging stack to compatible versions.
- Extends the packaged smoke test to import the real WinForms backend so this failure is caught during release builds.
The CPU Windows ZIP is recommended for broad compatibility. CUDA, Vulkan, Linux, and Apple Silicon macOS packages are also attached below.
